请帮我看看这篇文章有无语法错误?
good morning!/gooding afternoon!/good evering!all of you distinguished judges!
first of all,let me introduce myself.surely the former speechs of other students are wonderful,but i thought you may be a little bit tired.so let's be more excited now.Iam Ihy,a common student of experiment middle school.i am a little nervous,you must fought it,right?but in fact iam a outgouing boy.i have a lot of hobbys,such as playing badminton,playing pingping ball and so on.sometimes i am going to swim.and now,perhaps you may want to ask me one questionwhat's your enlgish name?i would like to tel you all seriously, i have no english name!i thought a true chinese need not english at all.i think,to learn english is just to make our country much more stronger.at the same time,i love english very much indeed!trust me!iam not a actor,so i thought i don't need to pretend to loving it.i love english,just from the deep soul of myself.that's why i am here!that's all!thank you very much for your listening!
有的话帮忙改下

第一行good afternoon
第三行speeches
第四行but换成and 因为没转折意思
so let's be more excited now这句不知道你要表达什么
you must fought it不太好 你是要说“你们一定感觉到了吧!”吗 you may feel that
Iam :i am
playing badminton,playing pingping ball 后面的playing可以不要了,以免重复
sometimes i am going to swim这是一般现在时不用一般将来时sometimes i go to swim
i thought a true chinese need not english at all.你是要说要不要英文名字不重要吗?i thought a english name is not necessary as we are chinese
pretend to loving it感觉有点别扭,我也不知道是不时用-ing形式,你再查一下喽!
